JEE Mains · Chemistry · STD 12 - 3. Chemical kinetics
The rate constant \((k)\) of a reaction is measured at different temperatures \((T),\) and the data are plotted in the given figure. The activation energy of the reaction in \(kJ\, mol ^{-1}\) is : (\(R\) is gas constant)

- A \(2\, R\)
- B \(R\)
- C \(1 / R\)
- D \(2 / R\)
Answer & Solution
Correct Answer
(A) \(2\, R\)
Step-by-step Solution
Detailed explanation
Slope \(=-\frac{E_{a}}{R}\) \(-\frac{10}{5}=-\frac{E_{a}}{R}\) \(E_{a}=2 R\)
